WD RE SAS and WD RE SATA drives

STORAGE VENDOR Western Digital (WD) expanded its line of enterprise class hard drives today, announcing that its WD RE SAS and SATA drives will now be available in capacities up to 4TB.

The drives are "the largest that Western Digital currently manufactures", and they top the WD range in 1TB, 2TB, 3TB and 4TB capacities for nearline SAS and 2TB, 3TB and 4TB for SATA models.

The 3.5in drives are "designed, tested and optimised for enterprise storage and applications" and give "up to 2.4 [petabytes] of raw capacity in a single enterprise rack," WD said in a statement.

Features of the hard drives include dual port, full duplex connectivity and "Notouch" ramp load technology so that recording heads never touch the disk media for less wear to recording heads, as well as Dual Stage Actuation (DSA) and Rotary Acceleration Feed Forward (RAFF) for better performance when the drives are used in vibration-prone multi-drive chassis.

WD said the drives also offer reliability with a five disk, 800GB per platter design, SAS interface and 6Gbit/s data transfer rates.

WD said the 4TB drives are available for around £320 from select distributers. µ
